Handle bar grip



Nov. 19, 1940. y c. ROBERTS HANDLE BAR GRIP Filed Aug. 28, 1939 INVENTOR ATTORNEYS Patented Nov. 19, 1940 UNITED STATES PATENT OFFICE HANDLE BAR GRIP Application August 28, 1939, Serial No. 292,355

3 Claims.

My invention relates to handle bar grips and has as one of the principal objects thereof the provision of a handle bar grip so constructed and arranged whereby ventilation is supplied to the 5 hands of a user during action, thus enabling the user to keep a secure grip upon the grip without the inconvenience and loss of efficiency arising from the slipperiness caused by perspiration which attends the use of grips of ordinary construction and without rendering the hands sore.

Another object of my invention is to provide a device of the character described which is simple in construction, durable in use, efficient in operation and economical in manufacture.

15 A further object of my invention is to provide a device of the character described capable of being readily applied to handle bars already in use without modifying the same.

Other objects and advantages will be apparent from the following description, appended claims and annexed drawing.

Referring to the drawing wherein like reference characters designate like parts throughout the several views:

25 Figure 1 is a side elevation of my invention illustrating the same applied to the handle bar of a bicycle or motorcycle.

Figure 2 is a side elevation of my invention on an enlarged scale and partly in section to more 30 fully illustrate the same.

Figure 3 is a sectional view taken on the line 3-3 of Figure 2.

Figure 4 is a detail sectional view of my grip taken on the line 44 of Figure 2.

35 In a preferred embodiment of my invention illustrated in the drawing, my novel form of handle bar grip 5 comprises a pair of spaced concentric inner and outer tubes 6 and 1 respectively, the inner tube 6 being imperforate and secured 40 about the outer end section of a metal handle bar 8 of a bicycle or motorcycle. The outer tube 1 is spaced from the inner tube 5 by a plurality of longitudinally extending ribs 9 and is formed with longitudinally extending rows of perforations ll] arranged between the ribs 9.

The outer surface of the outer tube 1 is provided with longitudinally extending ribs ll arranged between the rows of perforations Ill and which serve to form air passages when covered by 50 the hands of the user. The outer ends of both of said tubes are integrally connected together by an outer end wall l2 and the inner end of the outer tube 1 is provided with a flared portion l3, the ribs 9 extending through said flared portion.

55 The grip is preferably constructed of rubber but it is to be distinctly understood that the same may be constructed of other suitable material if desired.

In use, the grip 5 is arranged on the end of the 60 handle bar as illustrated in Figure 1 and the (Cl. i l-551.9)

flared portion at the inner end thereof causes air to be directed into said grip between the tubes and ribs 9 whereby said air is forced through the perforations I0, thereby preventing the users hands from perspiring while gripping the grip thus insuring a firm grip by the user at all times.

It is obvious that the invention is not confined to the herein described use therefor as it may be utilized for any purpose to which it is adaptable.

It is therefore to be understood that the invention is not limited to the specific construction as illustrated and described, as the same is only illustrative of the principles of operation, which are capable of extended application in advance forms, and that the invention comprehends all construction within the scope of the appended claims.

What I claim is:

l. A grip of the class described comprising a pair of coextending inner and outer tubes having open front ends with the front end of said outer tube formed with a flared portion disposed in circumspatial relation about the front end of said inner tube, circumferentially spaced and lengthwise extending ribs connecting said tubes together in spatiality and with the front ends of said ribs 25.

disposed within and connected to said flared portion for effecting confortaticn of said flared portion against distension by air directed between said ribs by said flared portion, said outer tube formed between said ribs with longitudinally extending rows of perforations, said tubes having a common rear wall closing their rear ends and coacting with the ribs for forcing the air outwardly through said perforations.

2. The structure of claim 1 including, said outer tube provided on its outer surface with ribs extending between said flared portion and rear wall and interjacent said rows of perforations for directing the air from the latter between the hand of a user and said outer tube.

3. A grip of the class described comprising a tubular member for disposition in surrounding relation to the handle bar of a. bicycle, said tubular member having an open front end formed with a flared portion disposed in circumspatial relation to the connected handle bar, circumferentially spaced and longitudinally extending ribs within said tubular member and lying in radially disposed planes passing through the axis of said handle bar and having their forward ends 5 disposed within and formed on the inner face of said flared portion for effecting confortation of said flared portion against distension by air directed between said ribs by said flared portion, said tubular member being formed between said ribs with longitudinally extending rows of perforations, and a wall closing the tubular member at the rear end and coacting with the ribs for forcing air outwardly through said perforations.
